The answer is B. The theory of isostatic equilibrium is used to explain the vertical height of a particular point on the earth such as the Himalayas. This theory is very similar to the principle of buoyancy. The mantle, in this case, is the liquid being displaced by the crust above. To accommodate great pressures such as those exerted by the Himalayas, the mantle distributes the force by height adjustments.
Answer:
The constants are such entities which are not replaced or can not be changed but they remain the same for each object or entity or we can just say that the properties of any space given remains the same all the way from the start of any experiment of activity to the end of it.
- Such as the mass,m , density,D, and the chemical bonding of the compounds and those objects under-consideration can not be changed or varied. In this case the mass of the plan made out of a certain material its density,D etc can not be varied.
- As the different properties can not be changed in any such way or mechanism, while there are certain factors which are termed as the designing of the objects and the entities which includes the factor of temperature,T , pressure,P and the volume,V of the vary entity under-consideration.
- While, the two group of students are provided by the specific manner and number of materials.As these materials can be improved by using the more advance form of instruments, as long as the technology exists the students will be able to control the different errors and improving there quality of work, as each measurement and experimentation requires more accuracy and precision for measuring the different factors.
Answer: D. Is an intrusive igneous rock
Explanation: Granite is an intrusive igneous rock which forms from the cooling and solidification of molten magma below the earth surface. Igneous rocks which forms below the earth surface are termed intrusive. Due to the intrusive nature of granite cooling and solidification occurs slowly hence, giving rise to coarse grained crystals large enough to be seen with the eye without the use of a microscope.
The extrusive equivalent of granite is basalt which is formed from the rapid cooling and solidification of magma above the Earth surface hence giving rise to fine grained crystals.
Answer: I believe it's A and D
Explanation:
Answer:
4.54 km of earth's crust lies within mantel.
Explanation:
- Earth's continental crust is made of igneous, metamorphic, and sedimentary rocks and is composed of SIAL elements. The continental crust is made of various layers and has a density of 2.83 g/cm, while the oceanic crust is about 2.9 g/cm.
- The ontientla crust has usual thickness of 40 km (25 miles) thick and floats or rests on upper mantel or i.e the asthenosphere. While other parts of it lies within the mantel the depth of the continental crust ranges to 100 km,
- where r/25 = 2.7 / 3.2
- r/25 = 0.82
- r= 0.82 x 25
- r= 20.46
- 25 - 20.46 is 4.54 km.
